This question is completely up to your personal experiences, and therefore I can't answer it unless I know you personally.
But I will give an explanation to what prejudice is so you can answer your question yourself.
<em>Prejudice is somewhat similar to discrimination, where you judge people based on what group they belong to (etc. race, gender, sexuality) without reason. Something similar to racism. People can be prejudiced because they belong to any group.</em>

I hope you can answer the question well. :)
The correct answer is B) low prices.
Indeed, big-box retailers are always located outside cities and towns in order to avoid local taxation. Unless you live in the area they are never located downtown (unless they enjoy a local tax exemption). These are industrial outlets that seek to maximize profit while using the cheapest, smallest workforce so personalized customer service is nonexistent. Their only advantage is low prices and for many low income consumers it is a crucial one.
